R-M2-9821	CY2-vitamin B12	CY2-Vitamin B12 is a fluorescently labeled vitamin B12 (cobalamin) conjugate, where CY2, a green-emitting cyanine dye (Ex/Em ≈ 490/510 nm), is covalently attached to vitamin B12. Applications: Cellular uptake studies – trace vitamin B12 internalization pathways. Targeted drug delivery – use B12 as a targeting ligand for cancer or deficiency-related therapies. In vitro and in vivo imaging – track B12 conjugates in biological systems. Diagnostic probes – for B12 receptor expression profiling.	price>
R-M2-9841	TCO-PEG-CY7	TCO-PEG-CY7/4e-TCO-PEG-CY7/4e trans-cyclooctene-PEG-CY7 is a multifunctional fluorescent probe composed. Applications: Pre-targeted imaging–conjugation with tetrazine-modified antibodies, peptides, or nanoparticles. In vivo optical imaging – tumor visualization and biodistribution studies. Click chemistry-based labeling – site-specific modification of biomolecules. Theranostic platforms – integration into drug delivery systems with real-time tracking.	price>
R-M2-9853	CY5-L-Tyrosine	Cy5-L-Tyrosine/L-Tyrosine,CY5 labed/Cyanine5-L-Tyrosine/ L-Tyrosine,Cyanine5 labed is a fluorescent amino acid conjugate, where the near-infrared dye Cy5 is covalently attached to L-tyrosine. This conjugate combines the biological relevance of tyrosine with the strong NIR fluorescence of Cy5 (λ_ex ~650 nm, λ_em ~670 nm), making it highly suitable for optical imaging and biochemical studies. Applications: Fluorescent labeling of peptides, proteins, or biomolecules. Cellular uptake and distribution studies with reduced background interference. Biochemical assays involving tyrosine-related signaling or enzyme activity. Molecular imaging in vitro and in vivo.	price>
R-M2-9854	CY5-Duramycin	Cy5-Duramycin is a fluorescently labeled peptide probe, where duramycin,a 19-amino acid lantibiotic peptide that binds specifically to phosphatidylethanolamine(PE) in cell membranes, is conjugated with the near-infrared dye Cy5 (λ_ex ~650 nm,λ_em ~670 nm). This construct enables highly sensitive optical imaging of PE-rich membranes. Applications: Live-cell and tissue imaging of phosphatidylethanolamine distribution. Apoptosis detection, since PE externalization is a marker of early apoptosis. Membrane biology studies involving lipid–protein interactions. Fluorescent probe for diagnostics in cancer, cardiovascular, and neurological research.	price>
R-M2-9855	CY5-Glycine	Cy5-Glycine/Cyanine5-Glycine is a fluorescent amino acid conjugate, in which the near-infrared dye Cy5 (λ_ex ~650 nm,λ_em ~670 nm) is covalently attached to glycine, the simplest amino acid.This conjugate provides a minimal fluorescent building block for bioconjugation, molecular imaging, and biochemical studies. Applications: Fluorescent labeling in peptide or small-molecule synthesis. Cellular imaging and biodistribution studies with low autofluorescence. Tracer for biochemical assays involving glycine metabolism or transport. Custom bioconjugation in drug delivery or nanomaterial development.	price>
